IQ test scores in childhood will predict many important things in adulthood—higher intelligence predicts higher education level, higher socio-economic status, higher salary, better health, greater civic participation,[4] lower impulsivity, and longer lifespan.[5] Lower intelligence predicts higher criminality, and shorter-term future-orientation.[6] In other words, people who are more intelligent tend to live for the future whereas people who are less intelligent tend to live for the now.
